A man who enjoys women flirting with and/or show off to other men
If you go to a stripclub, you are a cuck
Men who let other men fuck their wife.
"Man, Antonio is such a cuck, his wife sucks on other guys dicks.
Origin: A person (usually a man) who allows (and possibly even enjoys) cheating in his relationship. Not himself, but when his partner cheats. Lets his partner treat him like shit but still stays with them. Is probably also toxic to his partner (and maybe other people) in some way.
Other uses for "Cuck:"
1: Like a pushover or an idiot, but also an asshole. Could also fall under the origin of "cuck." Say some guy keeps getting back with some chick even though their relationship is toxic and they treat each other like shit and hate each other (similar to the original definition, but we're leaving out the weird cheating stuff for this example), but the sympathy for him isn't there. Because he's a total sack of dicks.
2: Basically just an asshole. A prick. But maybe more extreme. Like a really shitty person who's gross and just generally disgusts you. Or, to be more honest: this is what I think of it as, but I kinda just think cuck is fun to say.
"Wow, what a fucking cuck."
